Breakfast and Gastric Bypass …

Eating a healthy breakfast has an important role in fitness, particularly after an invasive surgery like gastric bypass.

Certain factors come in the way of a healthy breakfast, such as poor appetite, irritation, abdominal pain, or discomfort.

Also, it is vital to maintain a decent calorie intake for the sake of healing and recovery.

Most patients skip this meal for reasons like an irritated mood or being unaware of what to eat.

Their digestive tract is altered, so certain foods become unappealing, and patients also choose to eat significantly less, not to gain weight. However, not consuming food is the most unhealthy decision.


Nutritional Deficiencies After Gastric Bypass:

After gastric bypass, 30-70% of patients often have nutritional deficiencies. Among these most common deficiencies are protein, iron, zinc, folate, calcium, vitamin B1, B12, and vitamin D deficiency.

The decrease in meat and fish and small intakes of dairy products further aggravated the adequacy of proteins, iron, and zinc.

Similarly, reduced consumption of starchy foods and insufficient consumption of fruits and vegetables harmed fiber and soluble vitamins, particularly thiamine.

When severe nutritional deficiencies occur, they may lead to various symptoms, including anemia, hypoalbuminemia, edema, peripheral neuropathy (folate, B12), hair loss (protein), as well as Wernicke encephalopathy and beriberi (B1), a metabolic bone disease of vitamin D and calcium, and anemia due to iron deficiency.

Thus, for post-surgical management of patients, nutritional monitoring, quality of food, and quantity of food consumed should be considered in daily living to get better outcomes after the surgery.


Caloric Intake After Gastric Bypass Surgery:

Patients under post-surgical management reduce their daily caloric intake and their portion sizes.

After surgery, in the first few weeks, the postoperative diet generally provides 500-800 kcal/day, a very low-calorie diet.

Between 3 months and 1 year, calorie intake gradually increases from 800 to 1000 kcal/day.

Up to 5 years post operational calorie intake increases gradually but remains lower than the preoperative values. 

Dietary Energy Density (DED) After Gastric Bypass:

Dietary energy density (DED) is a term that varies from nutrient to nutrient in any meal.

The dietary energy density (DED) decreases significantly from 1.07 to 0.78 kcal/g 6 weeks after bariatric surgery and from 0.90 kcal/g to 0.96 kcal/g after 1 and 2 post-surgical years.

Among macronutrients, compared to proteins and carbohydrates, fats have the highest influence on DED due to their high energy content (4, 4, and 9 kcal/g, respectively).

In contrast, water-containing foods such as vegetables and fruits have low DED; thus, their excessive use has a good effect on DED as well as giving the feeling of fullness without increasing total calorie intake.


Liquid Intake After Bariatric Surgery:

Hydration is critical after surgery because it is the most common post-operative complication.

  • What to drink:

Water, milk, soy milk, protein shakes, decaffeinated tea or coffee (without added cream or sugar), and other non-carbonated and sugar-free beverages.

  • Amount per day:

64 to 100 ounces—progressing in volume throughout your post-operative diet stages.

  • What to avoid:

juices, caffeinated beverages ( including soda, coffee, tea, and energy drinks), carbonated waters, alcohol, lemonade, sweetened tea, sugary sports drinks, and any sugar-sweetened beverages.
